Hi - loved the Nurikabe while it lasted , pity they have stopped now .

I have found that the last puzzle posted (the big one) has three valid answers according to the rules . One of them has two 2x2 blocks of four white squares, one has one block, and one has no blocks. In all the rule sets for Nurikabe that I have seen, there is no mention of this not being allowed. Certainly a 2x2 block of black squares is disallowed, but not with white squares. There are nine squares which can change in three different cominations. I can post the three solutions if I someone is interested.

No comment at all from the PTB (or anyone else) about the multiple answers? Does anyone else out there agree or disagree that there are three possible solutions, as mentioned in the previous entry?
Curious

I like the format and look of the puzzles on this site better, though. There's another site that has daily 9x9 puzzles and I'm in the process of using that site to make some printable puzzles to satisfy my nurikabe craving.
